When Gamache receives a message from Myrna Landers, in the village of Three Pines, he welcomes the chance to get away from the city for a few hours. Myrna's longtime friend, who was due to spend Christmas in the village, has failed to arrive. When Chief Inspector Gamache presses for information, Myrna is reluctant to reveal her friend's name. Mystified, Gamache soon discovers the missing woman was once one of the most famous people not just in North America but in the world, and now goes unrecognized by virtually everyone except the mad, brilliant poet Ruth Zardo.
